I tem's, my more particular objectbeing toso connect the telegraphonewith line wires as to enable the instrument to be easily con trolledfrom a distance.

My invention further relates to provision for preventing undue waste ofthe available record s ace upon the movable -member bearing t e record.

My invention further relates to means whereby a person may leave atelegraphone in such condition that during absence of the person thetelegraphone will automatically receive a'messag'e intended for theperson and will, under pro er conditions, reproduce this message care-fu1y. i I

"My invention further relates to certain details of construction wherebythe general efiiciency of the telegraphone and parts associatedtherewith are generally improved.

Reference is, to be had to the accompany: ing'drawings -forming a partof this specification, -in which simllar characters of referenceindicate'corresponding parts in all the figures.

"Figure I is a diagram showing the wiring of my system, a delicate relayconnected with this wiring and adapted to be actuated by the human voicefor the purpose of controlling certain movable parts and thereby thesound record of the telegraphone, this view also showing means operatedelectricallyfrom a distance for startmg the telegraphone into act-ionand for, stopping its actlon upon the expiration of a predetermined timelimit; Fig. 2 1s a side elevation showing a part of the teleglraphonemechanism and casing containing t e same, certain parts being brokenaway. Flg. 3 1s a horizontal section through the casing showing thetelegraphone mechanism in cluding a revoluble dlsk sound record, meansfor cont-rolling a travellng carriage, and travcling magnetic mechanismco-acting with this record; this view further shows the reiay abovementioned, and also a part of the means'for starting and stoppingtheteleg- 55 raphone; Fig. 4 is an enlarged fragmentary section upon theline 44 ofiFig. 3, looking in the direction of the arrow and showing therecord disk, the magnetic mechanism coacting therewith. for recordingand reproducing sounds, and mechanism controllable from a distance forstopping and starting the travel of this magnetic mechanism; Fig. 5 is aplan partly in section, showing the relay controllable by the humanvoice for governing the motion of the magnets 35 relatively to thecenter of the disk 22; Fi 6 is a vertical section upon the line 66 0 Fi5, looking in the direction of the arrow an showing the contact forminga part of the relay 75, this contact being opened and closed: by soundcontrolled agency from a distance; Fig. 7 is a perspective of thearmature of the relay 75, this armature being controllable by so-calledmagnetic drag; Fig.- 8 is an enlarged fragmentary elevation of themechanism operated electrically from a distance for stoppmg and startingthe spring motor of the telegraphone, the casing 10 in this view bee ingshown in section and Fig. 9 is an enlarged fragmentary lan of the'worm71 and worm gear used or turning the screw 59 (see Fig. 8) incidental tostopping and starting the spring motor of the telegraphone.

A casing 10 is, by aid of hinges 11, mounted upoma base 12. Containedwithin the casing 10'is a ring motor 13 including variousgear whee s 14,15, and a winding shaft 16, the latter being provided with an outwardlyextending portion 17 and with a hand crank 18 whereby the spring motormay be wound in the usual manner. The spring motor also includes a bevelgear 19 which meshes with a bevel pinion 20; the latter being rigid upona revoluble shaft 21. A record disk is shown at 22 and is of theso-called magnetic type: This disk is mounted firmly upon the shaft 21and turnswhen the latter rotates. Mounted firmly u on the shaft 21 is aworm gear 23 which mes es with a worm 24. A governor is shownat 25 andis provided wlth a revoluble disk 26, the governcr and disk beingactuated by a shaft 27 inte gral with the worm 24. A spring contact 281s located 'ust below the disk 26 and is opened an closed .by movementsof this disk in the general direction of the axis of the governor shaft27. When the shaft turns,

the governor pulls the disk 26 to the left accordm to the view shown inFig. 5 and this closest econtact 28. Hence, while the telegllO ' nivot43 as a center.

raphone is in action, the contact 28 is closed, whereas this contact isopened when the telegraphone is idle.

Mounted rigidly upon the revolublei shaft 21 is a bevel gear 29 whichmeshes with a bevel gear 30 mounted rigidly upon a revoluble screw shaft31. A bracket 32 is located below the screw shaft 31 and is providedwith lugs 32*" disposed upon op osite sides of the screw shaft 31.Practica y speaking, therefore, the bracket 32 has its upper endbifurcated so as to straddle the screw shaft.v

' engaging the disk 22 so as to confer thereupon or to receive therefrommagnetic impulses corresponding to sound vibrations. A limiting stop 38(see Fig. 3) prevents excessive travel of the U-shaped spring 36 in onedirection. A stationary bracket 39,

having substantially the form of a Wedge, is

employed for the purpose of spreading the 'U-shaped spring 36 whenevernecessary, in order to adjust the tension or position of'thepointedcores 37 relatively to the disk 22.

For this purpose a handle 40 (see Fi 3) is provided; the operator merelyp s the handle outwardlyso as to force the Ushaped spring member 36astride of the wedge 39 and thus distend the U-shaped member to anydesired extent, the distension being continued until the U-shaped memberlodges against the limiting sto '38. A comparatively stiff rod 41 extenslengthwise of the casin Mounted upon this rod 41 is a tubular slide 42connected ri idly with the bracket 32 (see Figs. 2 and 4). Mounted upona screw pivot 43 is a rocker44 to which the blade'33, above described,is ri idly secured. This blade is provided wit a concave edge. 45 whichis, in effect, a fragmen tary threaded put adapted to engagev anddisenga e the screw shaft 31, so as. to force the bla e 33 and all partsconnected with it, in a general direction parallel with that. of

the screw shaft.

A leaf sp 46 is mounted upon the bracket 32 :35 engages the edge of therocker 44. a This rocker is provided with a slot 47 through which passesa screw 48 engaging the bracket 32. rocker-44 to tumor rock slightly u.on the "In oing. t 's the rocker brings the edge or thread 45 into and Yout of engagement with the screw shaft 31,

as above described. I Mounted rigidly upon This allows the the lower endof the rocker 44 is an'armature 49 adapted to be attracted and releasedby the magnet 34. The lower end of the bracket 32 is connected by apivot 50 with the U-shaped member 36. This allows the U-shaped member alittle freedom and widens its adaptability to conform to accidentalvariations in the shape of the disk 22, due, for instance, tounavoidable distortion or buckling of the latter. It also allows ease ofmovement of the bracket 32 and.

tubular slide 42 relatively to the rod 41.

I It will readily be seen that whenever the magnet 34 is energized, thescrew shaft 31 being in motion, the bracket 32 and all parts connectedtherewith, including the magnets 35, must begin to travel toward thecenter of-the disk and that this travel must cease when the magnet 34 isdenergized (see Fig. 4). It will also be seen that the disk, may rotatecontinuously although thetravel of the magnets 35 may be intermittent.

The disk 26, carried by the governor 25 (see Fig. 1), inaddition toopenin and closing the contact 28, serves as a bra e disk for stoppingand starting the action .of the spring motor. To this end a brake shoe51 is mounted upon a brake rod 52, the latter being rigidlyconnectedwith a rocker shaft 53 and provided with a rigid portion 54extending beneath an adjusting screw 55. By turning the'screw 55, theplay of the brake rod 52 and brake'shoe 51 may be controlled withindifferent limits. A spring 56 tends to retract the brake rod 52 and toremove the brake shoe 51 from engagement with the disk 26 whenever theshaft 53 is rocked in the proper direction for so doing.

Mounted upon the rocker shaft 53 is another brake rod 57 provided witha'concavebrake shoe 58. Disposed beloW- this brake shoe 58 and adaptedto engage the same, is .a screw shaft 59 provided with aslot 60extending throughout a good portion of its length. A threaded shoe 61,constituting in effect a fragmentary nut, is adapted to engage. anddisengage the screw shaft-59. The shoe 61, together with an armature 62is mounted upon a bell crank lever 63, the latter being movable andprovided with a retracting spring 64. A magnet 65 is disposed adjacentto the armature 62, and, when energized, draws the same. It will be seenthat when the magnet 65 is energized, the

threaded shoe 61 is removed from the screw shaft 59, and that when themagnet 65 is de.

energized, the retracting spring 64 instantly throws the threaded shoe61- into engagement with the screw shaft 59.

A; tube 66 (see Fig. 8) is fitted with an. adjusting screw 67, and forthis purpose is provided internally with threads68. This tube is mountedupon a bracket 69. A worm gear 70 meshes with a worm 71., the lattereing integral with a revoluble shaft 72.

shaft rotates within a bearing-"73 forming a part of a bracket 74 (seeFig. 9). The

' upper'end of the tube 66 is smooth and the' movement of the screwshaft.

When the motor 13 is in action, the shaft 72 and worm 71 rotate andcause the worm gear 70 toreturn. This gear is provided with a spline 70(see Fig. 9) which fits into the slot 60. The relation of the gear 70 tothe screw shaft 59 is, owing to the action of the spline, alittlepeculiar. When the gear 7 0 turns, the spline 7 0 causes the screw shaft59 to turn at the same rate of speed .25 as the gear 70, but at the sametimeleaves the screw shaft 59 free to ascend, descend, or to remain at agiven altitude, as the case may. he. If, now, the threaded shoe 61 happensto be in engagement with the screw shaft 59, the rotation of thelatter, of course, causes it to climb or to rise relativel to the shoe61, and if at any time the t eaded 1 shoe 61 be'withdrawn by action ofthe magnet 65 upon the armature 62 (see Fig. 7) the screw shaft 59 dro sabruptly down ward until stopped by t e adjusting screw 67.. Hence, allthat the ear 70 does is to turn the screw shaft 59 in ependently of thealtitude thereof, and all that the m net 65 40 does, actin through thethreaded s 0e 61,

is to cause the screw shaft 59 to rise gradual] or to fall abruptly asthe case may be. It, now, the magnet 65 he deenergized so that -thethreaded shoe 6] rests in engagement #5 with the screw shaft 59; for apredetermined length of time, say five minutes, the screw shaft 59 risesuntilitreaches the brake shoe 58 (see Fig. 8). It thereupon causes therocker shaft 53 to turn, and this movement brings the brake shoe 51against thefriction disk 26, thereby stopping the motor. By "moving theadjusting screws 55, 67 the pre cise duration of the movement, beforethe motor is stopped, may be varied within cer- 55 tain limits; InFig.9.5 is shown the magnctic. drag relay, controllable electricallyfrom a dis- -tance for the purpose-of energizing and deenergizing thecircuit-through the magnet 34,-and bydomg this, to exert control overmovementsof the telegraphone niagnets 35. The relay magnet is shownat--and is mounted upon a bracket 75. A ncvoluble disk 76- is madc ofmagnetic material and 65 constitutes the armature for the magnet 75.

. just the reverse of the action of the This disk is provided with asleeve 77 integral therewith and encircling the governor shaft 27 A hub78 also encircles the governor. shaft but is immovable relatively.

thereto. A pair of lugs 79, 80, of the shaft,

indicated in Fig. 6, are provided. Revoluhly mounted upon the lug 79 isan adjusting contact screw 81. Another screw 82 is mounted upon and"movable in relation to.

the lug '80. These lugs 79, are secured rigidly upon a disk 83 ofinsulating material,

this disk being provided with a radially disposed slot 83, as will beunderstood from A set screw 84 permits removal of the hub 78 and yetmaintains the hub rigidly in position when in use. A springtongue 86,preferably of platinum, is mounted rigidly upon the revoluble disk 76and engages the hub 78, as will'be understood from Fig. 5.

The arrangement of these parts is such that the rotation of the disk 76may be retarded slightly and the governor shaft 27 and hub 78 may turnahead a slight fraction of a revolution, the shaft 27 bein loose ascompared with the disk 76. In other words, the revo lution of thecontact sprin 86 constitutes an elastic connection from tlie disk 76 tothe shaft 27 and parts connected therewith, so that the relation of theshaft 27 and disk 76 is only approximate asto relative position. Now,.asindicated in Fig. 6', the spring tongue 86 normally engages the contactscrew 81. If, however, there be a slight motion of the disk 76, thecontact screw contact is broken and when the magnet is deenergized, thecontact is closed, this being ordinary telegraphic relay.

By means of screws 85 the disk 83, of insulating material, is at alltimes maintained rigid in relation to the hub 78. -In fact, all partsimmediately connected with the shaft 27 rotate therewith and are rigidin relation thereto, aside from the flexibility of the coupling hetweenthe disk 76 and the shaft, as above described.

Brushes S7, '88 are disposed adjacent to eachother, the brush 88 beingin electrical communication with the hub 78 and contact spring 86, thebrush 87 engaging a slip ring 89, as will understood from" Fig. 5. Thebrushes 87, 88 are the terminals of the local circuit of the relay, themain circuit thereof being through the magnet. 75. The

action of the relay is quite simple. The

magnet 75being energized, the disk 76 is drawn toward it and itsrotation slightly rctardod by its friction against the ma net cores. Theshaft 27, continuing its rota ion in the direction indicated by'the.arrow in Fig. 6, causesthe contact screw 81 to break engagement with thecontact spring 86.

the circuit through brushes 87, 88.

Referring again to Fig. 1, a telephone may be seen at 90 which ispreferably ofconsiderable power. From this telephone line wires 91, 92lead to binding posts93, 94. Adjacent to these binding posts are others95, 96, and connected withthe two latter are wires 97, 98 andatelephonic receiver 99. From the binding post 93 a wire 100 leads to acontact, button 101. Another contact wire 101 is connected by a wire 102with the magnet 65. From the latter a wire 103 leads to the relay magnet75 and from this magnet wires 104, 105, 106, 107 lead down to bindingposts 94, 95. Wires 108, 108 are connected with the telephone magnets35. A wire 109 connects the wire 108 with a switch blade 110.. A contactbutton 111 is disposed in the path of this switch blade. From thecontact button 111 a wire 112 leads upwardly and connects with a wire113. The latter leads toa contact spring '114 adapted to engage anddisengage another contact spring 115; this last contact spring 115 isconnected by a wire 116 with themagnet 34 used as above described, forcontrolling the travel of the telegraphone magnets 35. From the magnet34 a wire 117 leads upwardly to the brush" 87. The other brush -88is-connected by a wire 119 with the, contact 28. From the latter wires120, 118 lead to a local battery 121 This battery is connected by wires122, 123 with a pole changer 124; this pole changer has contact buttons125, 126, 127. The contact 'buttons 125,

127 are connected with a wire 128, the latter beingin turn connectedwith wires 112, 113. The contact button 126 is connected by a wire 129with wires 105, 125. The switchblade 110 is provided with an insulatedboss 110 for forcing the contact spring 114 against the contact spring115, as will be understood from the lower left hand corner of Fig. =1.

The action of my system is as follows: We

will suppose that the mechanism shown in. Fig. 1, with the exception ofthe telephone 90 50.

and line wires 91 92, represents the outfit of a subscriber, and thatthe latter wishes to absent himself'and have the system take down anymessa e which may be sent during his absence. Tie moves the switchbladel 10 into the position indicated, thereby causingit to closecontact between springs 114, 115.. The spring motor we will suppose isproperly wound 11p and, it makes no difference whether'it be leftrunningor idle. If it be left runnin the rotation of the screw shaft 59raisesthe atter until it engages the brake shoe 85, thus causin therocker shaft 53 to turn and bring the s 0e 51 against the disk 26,thereby preventing further rotation of the motor. This occurs in afewminutes, if

the switch blade 110 is placed in the position the apparatus inindicated in Fig. 1 and stain quo until the call is made. Suppose nowthat a subscriber at the telephone '90 wishes to make a communication.To all intents and purposes he rings in theusualbutton 101, switch blade110, contact button 101, wire 102, magnet I call this for-conveniencethe starting magnet) wire 103, relay magnet 75, wires 104, 105, 106,107, bind ing post 94, line wire 92, back to generator of telephone 90.This energizes the starting magnet 65 and causes it to attract its arma-The screw shaft 59, being new unture 62. supported, drops down upon thescrew-67 (see Fi s. 1 and 8). The pressure a ainst the 'ra e shoe 58being now relieved, t e retracting spring 56 causes the withdrawal ofthe brake shoe 51 from the disk 26. The spring motor mechanism nowstarts, having been previously wound, above explained. When the motormechanism starts, the governor 25 is thrown into action. This causes thedisk 26 to move laterallyto the right, according to the view shown in.Fig. 1, and closes the contact 28. The telegraphone is now in fullaction, except with reference to movements of the telegraphone magnets35 and parts carrying the same. Whether or not these magnets 35' andparts carrying the same are in motion must depend upon the position i ofthe rocker 44' (see Fig. 1) and this must in turn'depen'd upon whetherthe circuit through themagnet 34 is or is not completed",

the completion of this circuit being ultimately controlled by theelectrical conditionof the relay magnet 7 5, as above explained.

The calling subscriber now begins to talk and. inso doing he sendstalking currents 'over' the following circuit: telephone 90, line wire91., binding post 93,: wire 100, contact button 101, switch blade 110,contact button I01,

; wire 102, magnet 65, wire 103,- relay magnet 75, wires 104, 105,106,107, binding post 94, line wire 92, back to telephone 90. Thiscircuit is identical with the one above traced,

with the exception that at the tele hone 90,

it is the talking circuit instead of t e ringing circuit) The talkingcircuit, however, being weaker, as usual, than the ringing circuit, isunable to have much effect upon the magnet 65- and consequently isunableto cause this magnet to withdraw the shoe 61" from en'- agementwith the screw shaft 59. The reay magnet 75 being more sensitive,however,- is energized by the talking currents and the v disk 76 isattracted.

Owing to the magnetic drag, above described, the disk is retarded and asthe shaft 27 rotates under propulsion from the s ring motor, the contactis broken between t e contact spring 86 and the contact screw This opensthe local circuit which is as follows: Battery 121, wire 122,righthandmember of the pole changer 124, contact button 125, wire 128,wire 113, contact springs 11.4, 115, wire 116, magnet-34,

wire 117,-brush S7, slip ring 89, lug 79, contact screw 81, contactspring 86, hub 78, brush 88, wire 11'9, contact 28 (now closed), wire120, wire 118, back to battery 121. The battery circuit being thusopened, it follows that the magnet 34 must release its armature 49. Thiscausesthe rocker 44 to move under impulse from the leaf spring 46 (seeFig. 4) and therefore throws the fragmentary nut 45 into engagement withthe screw shaft 31. slide 4 2, and telephone magnets 35 now begin. tomove toward the center of the record disk. If the talking subscribercontinues his conversation quite steadily,- there is no interruption ofthe motion of the telegraphone magnets 35. Slight pauses between thewords and at the ends of sentences are not sufficient to interfere withthe action in the-slightest degree, for .the reason that the magnet 34can not be deenergized until the circuit is opened between the contactspring 86 and the contact screw 81 (see Fig. 6) and this can not occurunless the voicecontrolled currents through the line are stopped for alittle period of time, sufficient tore resent the length of time duringwhich the s raft 27 can travel without causing the electrical connectionto break. In any conslderable pause 1n conversation, however,

the electrical connection is broken for the nets 35 are enabled totravel.

reason that the contact screw 81 moves away from the contact spring 86.When this occurs, the local circuit, above traced, is again completed,the rocker 44 assumes the position indicated in Fig. 1, and the mag- Assoon, however, as the talking subscriber resumes his conversation, themagnet 34 is-deener- I travel.

than would be recorded under conditions where. the telegra hone magnetswould'continue to travel uring intervals while the sounds were not beingproduced. During all the time while the record is being made the screwshaft 59 continues to rise, as above described until it lodges againstthe brake shoe 5S, and this action, as above described, turns the rockershaft 53 and applies the brake shoe 51, seas to stop the action of theThe bracket 32, tubular the polarity of the battery 121 for service, theidea being that, when a call is made, the telegraphone will be throwninto action and its action will continue for a predetermined period,-sayfive minutes. Sup pose now that the absent subscriber returns and wishesto ascertain what message, if any, has come while he was away. He turnsthe switch blade 110 (see Fig. 1) to the right and into en ageinent withthe contact button 130. T 's breaks communication between contactsprings 114 and 115, thus 0 eni the circuit through magnet 34. Be oreiloing this, however, he adjusts the magnets 35 in the usual manner soas to enable the telegraphone to act as a reproducer. The switch blade110 now resting upon the contact button 130, the following circuit iscompleted: Switch blade 110, contact button 130, wire 131, binding post96, Wire 97, receiver 99, wire 98, binding post 95, wire 106, wire 108,tele 'raphone magnets 35,wire 108, Wire 109, bac to switch -blade 110.This circuit is energized by the magnetic action of the disk upon themagnets 35, and, of course, the operator is enabled to read from thereceiver 99 the reproduction of the sounds representing the messagerecorded. If, as is usually the case, the subscriber now wishes to erasethe ma netic record from the record disk 22, he simpfiy turns the switchblade 110 to the left, causing it to engage contact button 111. Thismovement breaks connection between the contact springs 114, 115, andcompletes the following circuit: Battery 121, wire 122, right-handmember of pole changer 124, contact button 125, wire 1'28, wire 112,contact button 111, switch blade 110, wire 109, wire 108, telcgraphonemagnets 35, wire 108*, wire 106, wire 105, wire 129, lefthand member ofpole changer 124, and wires 12 3 and 118, back to battery 121. Thisenergizes the magnets 35, and by causing them to act powerfully upon therecord disk 22, the magnetic impressions upon this disk for representingsound vibrations are effectively erased. During this operation the disk22 rotates and the magnets 35 travel in the same manner as if themachine were reproducing or recording.

I find it sometimes expedient to reverse urposes of removing magnetic imrcssions om the disk 22. In order to do t is, I simply shift the olechanger 124'to theleft, meanwhile turning the switch blade 110, thuscompleting the following circuit: Batter 121, wire 112, right-handmember of pole c anger 124, wire 129, wire 105, wire 1'06, wire 108,magnets 35, wires 108, 109', switch blade 110, contact button 111, wires112, 128, left-hand member of pole changer 124, wire 123, wire 118, backto battery 121. i
